Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed August 18, 192). Serial No. 404,400.

To all whom t may concern Be it known that l, HERMAN MEGKING, a citizen on? the United States, and a resident of the city of New York, borough of the Bronx, in the County of Bronx and State 0i New York, have invented a new andlm; proved Gate for Dyumping'rucks, of lwhieh the following is a ulhclear, and enactfde scription. l

The invention relates to end gates for dumping trucks as shown and described in the application for Letters `Patent of the United States, No. 318,827, filed by me on August 20, 1919.

T he object of the invention is to provide a new and improved lgate for endwise dumping on automobile or power driven trucks or for sidewise dumping on railroad cars and the like, and arranged to insure an automatic opening of the gate on swing-ing the body into dumping position.

Another object is to prevent dirt or other line particles of the load from lodging in the joints between the body and the gate thus insuring free opening movement of the ate.

g Another object is to locate the locking means for the gate out of the path of the material sliding out of the body during the dumping operation, thus preventing injury to the locking means and allowing the material to slide unobstructedly out of the body.

Another object is to securely hold the gate in locked position at the time the truck body is in horizontal or loading position.

VJ ith these and other objects in view, the invention consists of certain novel features of construction as shown and described here inafter and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters oit' reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the gate in closed position on the rear endv of an automobile truck;

Fig. 2 is a similar view of the same with the truck body swung into dumping position and the end gate into open position;

Fig. 3 is a plan view of the gate as applied and in the closed position shown in Fig. 1; v

Fig. e is a sectional plan View of part of the improvement on the line of Fig. 1V;

Fig. 5 is a similar view of the locking means for locking the gate in position on the truck body, the section being on the line of Fig. 1; and Y l Fig. 61s a rear end .elevation of the same.

@n the. roar end of theframe 10 ofthe eutemebile trunk is SecuredY 'a transversely extending bar 0r beam ll on which eretta tncl upwardly extending lues v412 through which passes a transverse pivot 13 also/'pass'-` ingy through lugs 1e attached to transverse beams 15 and 16 secured to the under side of the truck body 17 near the rear end there of, as plainly shown in Figs. 1, 2 and 3. The truck body 17 is provided with additional transverse beams 18 and on the latter and the transverse beam 15 are secured side bars 19 adapted to rest on wearing plates 20 attached to or forming part of the frame l0, By thel arrangement described,V the truck body 17 is normally supported in horizontal 01." leading posities and the truck boefl? can be readily swung into dumping position, as indicated in Fig. 2, without interference with the rear traction wheels of the automobile truck and with the rear end of the truck frame l0.

The bar or beam 11 is provided at the sides with brackets 25 to which are secured upwardly and rearwardly extending' side members 26 between which extends the rear portion of thetruck body 1'7fwThe upper ends of the side members 26 are provided with transverse pivots 27 on which are mounted to swing filling pieces 28 secured to the front tace of a gate ortailboard 29 at the sides thereof. The forward edges 30 of the filling pieees 2 6 are'segmental and fit onto correspondingly shaped "rear edges 31 of the sides ot the truck body 17 to provide segmental joints between the filling pieces 28 andthe rear ends of the sides of the truck body 17 at the time the latter is in horizontal or loading position and the gate 29 is in closed position. It will be noticed that the gate 29 when in closed position extends approximately vertically and theV gaps between the end gate 29 and the sides of the truck body 17 are closed by the lling pieces 28 thus preventing the dirt orother material forming theload from dropping out of the body during the time the latter is in horizontal position.

In orderv to securely lock the end gate 29 in closed position and to insure a. firm conen between the @dass 30 and 3l, the telf lowing arrangement is made: On each side of the truck body 17 and the gate 29 are two coacting locking members el() and l1 for locking the end gate in position and drawing it iirinly into place. 'lhe locking member 40 on each side of the truck body 17 is in the 'form ot a. hook and located outside et the open end ot the truck body 17 so as to be completely out ot the way ot the load sliding out ot the open end of the truck body 17 at the time the latter moves into dumping position. lach locking member a0 is pro-` vided with a bracket 42 fastened by bolts or other fastening devices 43 to a transverse beam de secured to the under side ot the truck body 17 at the Vrear end thereof. The other locking member r1 on each side or" the end gate '29 is preferably in the term ci a friction roller journaled on al stud 46 projecting from a bracket 17 bolted or otherwise tastened to a cross beam 4:3 attached to the outer tace ot the end gate 29 at the lower end thereof to reinforce the said end gate besides forming a support tor each ot the brackets L17. The forward edges oli' the locking members l0 are cam-shaped to insure a tight closing ot the end gate 29 at the time the truck body 17 swings downward into horizontal position, and the triction rollers forming the locking members al engage the cam faces of the locking mem bers 40. v

When the truck body 17 is in horizontal or loading position, as shown in Figs. 1 and 3, then the end gate 29 is locked against opening by the lockingmembers 41 engaging the locking members 40. l/Vhen the truck body 17 swings into dumping position, as shown in Fig. 2, then the locking members l0 swing downward with the rear end ot the truck body and consequentlyl the locking members 40 move out ot engagement with the locking members 411 mounted on the tailboard 29 hung on the lined pivots 27. llhcn the truck body 17 swings back to its normal horizontal position then the locking members l1 reengage the forward cam Jfaces ot the locking members 40, and the upward movement ot the locking mem bers Ll0 moves the locking members 41 'torwardly thus firmly seating` the segmental edges 30 ot the fillingr pieces 28 of the end gate 29 on the segmental rear edges 31 oi the sides ot the truck body 17. Thus by the :urrangement described the end gate Q9 is securely locked in place and a rm joint is had between the contacting edges 30 and 31 thus preventing the dirt or other material. loaded into the truck body 17 'from lodging in the joints and obstructing the tree opening movement of the end gate as above eX- plained. lt will further be noticed that the locking members 40 and lll are completely out ot the way ot the material sliding out of the truck body 17 at the time the latter moves into dumping position, and hence the looking members L10 and L11 are not liable to be injured by stones, rocks or other material constituting the load, and the locking members l() and Ll1 are not liable to obstruct the material as the latter passes out through the rear open end et the truck body 17. By reference to Fig. 2 it will be noticed that the gate or tailboard 29 is tree to swing rearwardly and upwardly at the time the truck body 17 is in dumping position thus allowing` rocks or other large matter contained in the truck body and sliding out of the same to pass the gate. lf desired, the gate or tailboard 29 can be swung by the operator upwardly and forwardly into completely open position.

against the rear edges of the side members 26 abut blocks 50 bolted or otherwise secured to the outer faces ot the sides ot the truck body 17, the said blocks forming supports tor the side members 26 at the time the truck body 17 moves downward into horizontal or loading position. By the arrangement described the side members 26 are not liable to be bent out ot shape and hence the end gate 29 is at `all times tree to swing into open or closed position on moving the truck body 17 into dumping position or back into horizontal or loading posit-ion `Having thus described my invention, I claim as new and desire to secure by Letters Patentzm 1. A dumping truck, comprising a truck trame, a bracket attached to the said truck trame, a body mounted to swing on the said bracket and having a dumping opening, a gate hung at its upper end on the said bracket and normally closing the said dumping opening, triction rollers journaled on the sides et the said gate at the lower tree end thereof, and hooks adapted to be enrfaged by the said friction rollers to lock the gate in closed position, the said hooks being iiXed on the said body on opposite sides of the said dumping opening.
